After a day of seemingly non-stop calls and rearranging crews I final have a group of high school grads ready to go head-to-head with our tuna. Pushed east toward the south end of the Baltimore canyon. With 30 mile to go I take a peek at my cell phone to view my downloaded sea surface temperature satellite image only to realize the image is total junk. Arrive at the canyon to find 57 degree water in what was to be 65 degrees. We run south 20 miles to hopefully find some warmer water. Joey sets the spread and I point the boat east toward the 1000 fathom edge. After about a hour we the water temp reaches 63 degrees and 5 minutes later our center chain get blasted by a 35 lb yellowfin. Another pass and our long rigger get crushed by a very stubborn 25 pounder. The next two hours produce one explosion that completely misses the bait. With less than 30 minutes left in the day we get nailed by two more yellowfin. One misses the hook but the other comes tight and after a epic battle joins the other tow in the box. We pull in lines and I point her west with 68!! mile to OC.
